| Abstract |
Objective
The aim of this study was to investigate the characteristics of prosthetic gait of unilateral transfemoral amputees on an inclined surface compared with those of normal persons.
Method
Five male unilateral transfemoral amputees and ten normal persons were recruited. Uphill and downhill walking of inclined surface on slopes of 10 and 20 degrees and level walking were investigated. Kinematic data were obtained with VICON 370 system (Oxford Metrics Ltd., UK).
Results
The kinematic data of the transfemoral amputees showed significantly decreased peak hip extension at all situation and peak hip flexion at 20 degrees uphill walking,significant increased knee extension at 20 degrees downhill and all uphill walking, and significant decreased knee flexion at all situation, and significant decreased ankle dorsiflexion at all situation and plantarflexion at all situation except 20 degrees downhill walking compared with those of normal persons. Also they showed significant decreased cadence, speed and increased step time, double support at all situation compared with normal persons.
Conclusion
Analysis of prosthetic gait of unilateral transfemoral amputees on an inclined surface support the basic data for induction of normal gait pattern. (J Korean Acad Rehab Med 2006; 30: 69-73) |
